There were 40 new fields discovered in South Texas during the past year. In addition 58 new sands in the older fields were proved for production. This record is exceeded only by the year 1937 and exceeds the records of other years both in the number of discoveries and in probable additions to reserves.

The outstanding feature has been the development of important production from the Frio-Vicksburg along the updip side of the coastal province. This sand group has furnished some production in the past but discoveries during 1938 place it among the major oil-producing zones in the district. Of the discoveries, 8 fields and 27 sands were from this zone. Probably the more important of the fields are Alice in Jim Wells County, Kelsey in Jim Hogg County and Sun in Starr County.

The downdip side of the coastal province again furnished substantial additions to reserves with 9 new fields, numerous extensions and additional sands. Of these new fields Cordele, West, and Francitas in Jackson County; and La Rosa and Melon Creek in Refugio County offer the most promise; and, as a group, are probably the year's greatest contribution to South Texas reserves.

The Jackson trend continued to lead in the number of discoveries with 16 new fields. Excepting Fitzsimmons in Duval County, most of these may be relatively small.

Likewise the 6 Cretaceous fields opened in the fault line may have small recoveries.
